To the left is the classic photograph which has not only been reproduced a myriad times by structural geologists the world over, they have also looked forward to similar patterns in their own field areas. This is the photograph that Prof John Graham Ramsay, FRS, took in 1956 in the Loch Monar area of the famous Caledonian Scottish Highlands. The superimposition of this type, as well known to all, results when the hinges and axial surfaces are both folded about the axes of late folds. A typical "mushroom" would however result when the hinges of early folds are folded about axes and axial surfaces of late folds that nearly lie transverse or subperpendicular to them.  Below is a map of pattern covering an enormous area (25 by 18 km) in the early Proterozoic Aravalli mobile belt in western India. The map* (done up in 1936 and called HAMMER-HEAD syncline) is reproduced after Dr A M Heron of Geological Survey of India (who passed away in 1964 in transit on way to New Delhi to attend the International Geological Congress).
